I'm looking for two short, older fics:

First one has Dean being all NC-17 with four or five either shapeshifters or succubi that look like Sam.  Either way, they are essentially sexing him to death, and he's letting it happen because he thinks it's the only way he'll ever be intimate with Sam.  The real Sam rescues him at the end.

Second one is a phonesex fic where Dean is on his way back to Sam in the Impala, and he's dirty talking to Sam.  I think it ends when he arrives where Sam is.  Established relationship.  I'm pretty sure it was called "Are You Close?"

Thanks in advance!

ETA:  Both found in comments - thank you!
